SPECIFICATION forming part of Letters PatentNo. 705,345, dated J'nly22, 1902.

Application filed Iebruary l l, 1902. Serial N5. 945601. (No model.)

Toall whom it may concern:

Beit known that LGEORGE L. HALL, a citi zen of the United States of America, residing in the borough of Brooklyn, city of New York, county of Kings,and State of New York, have'invented certain new and useful Improvements in Rail-Joints, of which the following is a specification, reference beinghad therein to the accompanying drawings.

My invention relates to joints betweenadjacent rails of a railway and to the insulation of one rail from the rail adjacent to it; and its objects are to provide a strong joint and an economical use of and means ofapplying insulating material.

To these ends my invention consists, broadly, of a rail-chair having its bolt-plate on one side of the rail ends and extending across the joint, a metal band on the other side of the rail ends, also extending across the joint, two blocksof strengthening and insulating material,'one on either side of the accompanying drawings, inwhich similar nu-f inerals of reference indicate similar parts throughout the various views, 'of which- Figure 1 is a plan view, partly in section.

Fig. 2 is a side View. Fig. 3 isjan endview,

partly in section, on line 3 30f Fig. 1; and

Fig. 4 is a partial view, also on line 3 3 of Fig.

1, showing a modification.

l 1 are ends of two railway-rails to be joined and electrically insulated from each other.

2 is a rail-chair, the one shown being described in application for Letters Patent filed 6 represents insulating material between bridge 4 and rail ends 1 and is held in place by lugs 7, pinching tongues or laps of said insulatin'g material upon railends'L'as shown in Fig. 3; but I do not limit myself to this method of holding said insulating material in place.

' Between bolt-plate 3 and rail ends 1 and rate from the chair, insulating material 6 may be renewed easily.

11 represents bolts passing through boltplate 3, block 8, rail ends 1, block 9, and band 10 and adapted to hold the parts in proper relation with each other.

12 represents insulating thimbles' or bush- D :ings adapted to insulate inthe well-known manner all of bolts 11 passing through one of rail ends 1 from both the bolt-plate 3 of rail chair 2 and the band 10.

13 represents washers for the protection of i said bushings 12.

:Letters Patent filed by me February 10, 1902, Serial No. 93,276.

Said insulating material is provided with a tongue 15, adapted to mesh v with or be inserted in mouth or recess 16 in said plate 4. By thus holding said insulating material in place upon the bridge-plate by means independent of the'other parts of 'the joint an easy method of renewing said insulating material is provided; but I do'notchair having a bridge-plate and a bolt-plate, insulating material between the rail ends and said bridge-plate, a metal band separate from said chair and opposing said boltplate and extending across the joint, two insulating-blocks one between said bolt-plate and the rail ends and the other between said band and the rail ends and both extending across the joint, a plurality of bolts extendingthrough the bolt-plate, insulating-blocks, rail ends, and band, insulating bushings adapted to insulate every of said bolts passing through one of the rail ends from both said bolt-plate and said band, and means for maintaining the rail ends from contact with each other.

2. Aninsulated rail-joint comprisingarailchair having a spike-plate for spiking said chair to the ties, a bridge-plate and a boltplate, insulating material between the rail ends and said bridge-plate, a metal band separate from said chair and opposing said boltplate and extending across the joint, two insulating-blocks one between said bolt-plate and the rail ends and the other between said band and the rail end and both extending across the joint, a plurality of bolts extending through the bolt-plate, insulating-blocks, rail ends, and band, insulating bushings adapted to insulate every of said bolts passing through one of the rail ends from both said bolt-plate and said band, and means for maintaining the rail ends from contact with each other.

3. An insulated rail-joint comprising a railchair having a bridge-plate and a bolt-plate, insulating material between the rail ends and said bridge-plate, means for holding said insulating material in proper position on said bridge-plate independent of the other parts of the joint, a metal band separate from said chair and opposing said bolt-plate and extending across the joint, two insulatingblocks one between said bolt-plate and the rail ends and the otherbetween said band and the rail ends and both extending across the joint, a plurality of bolts extending through the bolt-plate, insulating-blocks, rail ends, and band, insulating-bushings adapted to insulate every of said bolts passing through one of the rail ends from both said bolt-plate and said band, and means for maintaining the rail ends from contact with each other.

4. An insulated rail-jointcomprisinga railchair having a spike-plate for spiking said chair to the ties, a bridge-plate and a boltplate, insulating material between the rail ends and said bridge-plate, means for bolding said insulating material in proper position on said bridge-plate independent of the other parts of the joint, a metal band separate from said chair and opposing said boltplate and extending across the joint, two insulating-blocks one between said bolt-plate and the rail ends and the other between said band and the rail ends and both extending across the joint, a plurality of bolts extending through the bolt-plate, insulating-blocks, rail ends, and band, insulating bushings adapted to insulate every of said bolts passing through one of the rail ends from both said bolt-plate and said band, and means for maintaining the rail ends from contact with each other.

5. An insulated rail-joint comprising a railehair having a bridge-plate and a bolt-plate, insulating material between the rail ends and said bridge-plate, means for holding said insulating material in proper position consisting of a tongue of the same adapted to be inserted in a mouth in the bridge-plate, a metal band separate from said chair and opposing said bolt-plate and extending across the joint, two insulating-blocks one between said boltplate and rail ends and the other between said band and the rail ends, and both extending across-the joint, a plurality of bolts extending through the bolt-plate, insulatingblocks, rail ends, and band, insulated bushings adapted to insulate every of said bolts passing through one of the rail ends from both said bolt-plate and said band, and means for maintaining the rail ends from contact with each other. 4

6. An insulated rail-joint comprising a railchair having a spike-plate for spiking said chair to the ties,a bridge-plate and a bolt-plate, insulating material between the rail ends and said bridge-plate, means forholding said insulating material in proper position consisting of a tongue of the same adapted to be inserted in a mouth in the bridge-plate, a metal band separate from said chair and opposing said boltplate and extending across the joint, two insulating-blocks, one between said bolt-plate and the rail ends and the other between said band and the rail ends, and both extending across the joint, a plurality of bolts extending through the bolt-plate, insulating-blocks, rail ends, and band, insulating-bushings adapted to insulate every of said bolts passing through one of the rail ends from both said bolt-plate and said band, and means for maintaining the rail ends from contact with each other.

In witness whereof I have hereunto set my hand this 13th day of February, 1902.
